What do I do if I cannot unscrew the head of my iSi Whipper?

First release the pressure: Place the whipper with the head upwards and hold a towel over the outlet. Activate the lever until the iSi Whipper is no longer under pressure. Now the head can be removed from the bottle. If the head still cannot be removed, please contact iSi or your service center.

What should I do if my whipper has a leak or releases pressure prematurely?

Ensure that the decorator tip is securely screwed on before using the chargers. Make sure that the head gasket is inserted and not damaged. Check that the whipper head has been properly cleaned. Follow the cleaning instructions given in the accompanying whipper instructions. If you add other ingredients to the cream, ensure that these are dissolved or stirred in. Otherwise clumps may form, blocking the dispensing system. A blocked dispensing system may cause leaks.

What do I do if after being cleaned in the dishwasher, my whipper has a kind of white film on the head?

Check the whipper instructions to ensure that your whipper is actually dishwasher-safe. Under certain circumstances, such as at high cleaning temperatures, with too long a contact time, or too high a pH value of the cleaning agent, it can happen that a light white or gray-colored film can build up on the metal head. This does not impair the functionality of the whipper in any way. Do not scrape. Do not use scouring agents.

How long does the mixture keep in the iSi Whipper?

Preparations can be kept in the refrigerator for up to 1 week thanks to the air-tight system.

How do I know whether my iSi Whipper is suitable for hot preparations?

Only iSi stainless steel whippers with a red silicone ring are suitable for hot preparations.

How can I dispose of the chargers? Can the chargers be recycled?

Please dispose of your iSi Chargers in a waste metal bin, sometimes referred to as "blue waste." Chargers placed in these bins can be recycled.

Can I use bottle components from other companies with iSi components?

You should only use iSi original components. The individual components of iSi Whippers are tailored to work perfectly together. Never combine your iSi Whipper parts with those from other manufacturers as we cannot provide a guarantee for them. iSi heads are marked on the head and charger holder. iSi bottles are marked on the base.

How to produce a cold brew coffee?

There are many variants of a basic formula: cold water, coarse coffee grounds, and an overnight brew. Depending on the recipe used, the steeping process takes from 624 hours. iSi recommends using about 5 tablespoons coffee grounds (set grinder to most coarse setting) with a 1:8 water to coffee ratio and a steeping time of about 15 to 18 hours.

Why is my Nitro-Coffee not cascading?

The cascading effect is closely related to the coffee used to produce the cold brew coffee. We recommend a coffee stronger roast (Arabica beans) with a high amount of protein.

Can I make whipped cream with the iSi Nitro?

No, this is not possible. The iSi Nitro is not compatible with any cream chargers available on the market. To prepare fresh whipped cream, please use any original iSi whipper that works with iSi cream chargers.

Do the Nitro-chargers contain liquid nitrogen used for instant-freezing?

No, iSi Nitrochargers contain pure compressed nitrogen gas.

What is the difference between Cold Brew and Nitro Coffee?

Nitro Coffee is nitrogen infused Cold Brew Coffee, similar in appearance to an Irish stout beer, creamy in taste, smooth in mouthfeel and full of coffee aroma without the often bitter taste of hot brewed coffee.

Nitro Coffee is based on cold brew coffee that is steeped over multiple hours and therefore more caffeine is released into the coffee compared to hot brewed coffee.

How long can I store my Nitro Cold Brew in the fridge?

Up to 5 days, but cascading effect will slow down slightly after each serving and over time.

How many chargers do I need for the iSi Nitro?

Only 1 charger is required to prepare Nitro Coffee in the iSi Nitro.

What is the difference between Nitro Cold Brew from a tap-installation and the iSi Nitro?

There is none. Taste and foam head are similar, but the iSi Nitro offers an electricity independent, mobile, maintenance free, easy to use solution. No taps, no tubes, no hassle.

Why can’t I use a Nitro Charger that fits in a charger holder for cream whippers?

There are Nitrogen chargers available on the market that fit in a chargerholder for cream whippers.

WARNING: Do not use those chargers in your cream whipper.

These chargers are NOT produced by iSi and pose a significant risk hazard. Especially related to devices with plastic heads, the 3 times higher pressure in these Nitro chargers can lead to serious injuries. Cream whippers are not designed for these high-pressure ranges and therefore must never be used with Nitro chargers. For this reason, the “Original iSi Nitro” and the matching “Original iSi Nitro Chargers” are also not compatible with available nitro chargers for cream whippers.

Are iSi Nitro Chargers compatible with other iSi whippers?
